 * @assertion Let S be the runtime type of o. In checked mode:
 *    • If the body of f is marked async it is a dynamic type error if o is not
 * null and Future<S> is not a subtype of the actual return type of f.
 *    • Otherwise, it is a dynamic type error if o is not null and the runtime
 * type of o is not a subtype of the actual return type of f.
 *
 * @description Checks that compile error is raised if o is not null and
 * the runtime type of o is not a subtype of the actual return type
 * of the immediately enclosing function.
